FCSA System Connections
FCSA System Connections
An FCSA has three primary system connections:
•
Data transfer interface (ServerNet) (connects to the ServerNet X and Y fabrics)
•
Maintenance entity (ME) interface
•
Power interface
These connections are on the back of the FCSA and attach to the midplane.
Data Transfer Interface (ServerNet)
The data transfer interface consists of ports to the ServerNet X and Y fabrics. The
ports connect to the ServerNet addressable controller (SAC) on the adapter. If one
ServerNet fabric fails, the FCSA can still be accessed by using the remaining fabric.
Maintenance Entity (ME) Interface
The Maintenance Entity (ME) interface contains the circuitry required to meet the
maintenance system requirements of an active-logic adapter, which includes:
•
Redundant access to the maintenance-system features of the adapter, which allow
you to:
°
Power the adapter on or off
°
Identify the type, configuration, and revision of the adapter
•
A serial EEPROM (SEEROM) that provides:
°
Hardware identification (part number and revision)
°
Manufacturing tracking (serial) number
°
Hardware-error data
Power Interface
The FCSA receives power through a shielded, high-density, metric connector module.
The connector module provides attachments to the two ServerNet fabrics.
Firmware
Flash Boot Firmware
The flash boot firmware contains version information about the boot firmware located
in the FCSA FLASH memory. The boot firmware runs on every FCSA after power on
and after hardware or firmware errors, and is re-downloaded to initialize the adapter
and to accept downloaded firmware from the processor.
